Hitachi has launched a new 3.5-inch hard disk drive with a capacity of 400GB, higher than any other drive in this class, the company announced Wednesday. The drive has been designed for audio/video applications, and particularly with digital video recorders in mind, Hitachi said in a statement.

The Deskstar 7K400 includes a technology called Streaming Command Set which optimizes the drive for storing and retrieving digital video content. The new drives will ship with Parallel ATA and Serial ATA storage interfaces providing data transfer speed of 1.5 Gbps (bits per second).

The drive consists of five disk platters with a rotational speed of 7,200 rpm and an average seek time to retrieve a piece of data of 8.5 milliseconds.

The new higher capacity enables users to store 400 hours of standard TV programming, 45 hours of high-definition TV programming, or over 6,500 hours of high quality digital music, Hitachi said.
